Please edit the file /etc/MailScanner/MailScanner.conf according to
your needs. Then configure sendmail or exim for use with mailscanner.
After you are done you will have to edit /etc/default/mailscanner as
well. There you will have to set the variable run_mailscanner to 1,
and then type "/etc/init.d/mailscanner start" to start the mailscanner
daemon.
